Neither fact has the Chicago native resting on his laurels as he participates in USA Basketball's minicamp this week.

"I don't think I'm a lock at all (for the 2016 Olympics)," Davis said Tuesday. "I have to earn my spot."

Davis averaged 3.7 points and 2.7 rebounds as the youngest member of the 2012 U.S. team in London.

"It was a great experience," he said. "I had a lot of fun, and the guys really taught me a lot about hard work. Hopefully, I can bring everything I learned to minicamp here and make the national team moving forward."

Coach's corner: Team USA coach Mike Krzyzewski invited former Olympic coach John Thompson to address the minicamp participants after practice. The two matched wits twice in Duke-Georgetown battles.

"He and I are great, great friends," Krzyzewski said. "He's one of the legendary figures, not just in basketball but in our country. When you think of the progress we've made with race relations, you have to consider John as one of the key people in that regard.

"All of those guys know who he is. If you could've seen their eyes fixated on him, it was like, 'Whoa.' It was good of John to do that."

Roster roulette: In a bookkeeping move that might not preclude an invitation to training camp, the Bulls waived summer-league standout Malcolm Thomas.

Thomas, who averaged 1.7 points in seven games last season for the Bulls, signed a contract that would've become guaranteed for $250,000 on Wednesday. With the Bulls past the luxury tax threshold, his guaranteed money would've cost them more at the end of next season.

The Bulls have 12 players under contract and remain in the hunt for veteran center Marcus Camby, along with the Heat and Rockets. If Thomas doesn't sign with another team, he could be invited back to Bulls camp. However, his chances of making the regular-season roster always were a long shot.
